Hose courtiers.

Application filed December 17, 1923, Serial No. 681,044.A

To all whom it may concern:

Be it known that I, HARRY A. WoLco'r'r,

a citizen of the United States of America.,

residing at Howard City, in the county of 6 Montcalm and State of Michigan, have invented certain new and useful Improvements in Hose Couplings; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hose couplings and is particularly concerned with an improvement in the construction of hose coupling shown in Patent No. 1,356,126 issued October 19, 1920, the present construction having all o-f theJ advantages inherent in the construction shown by said patent and having the further advantage that as the coupling is clamped against the hose, the bolt used is shortened in its effective length instead of lengthened, making buckling of the bolt impossible, a direct tensile stress being taken by the bolt instead of one directly the opposite. At the same time, the cost of production is lesscned, the bolts used being of regular stock formation and not special as in the construction referred to in said patent. Furthermore the construction is simply and economically made from sheet metal by dies at very low cost of manufacture. The invention consists in novel constructions and arrangements of parts for the effective attainment of these ends together with others not at this time specifically set forth, but which will appear as understanding of the invention is had from the following description, taken in connection with the accompanying drawing, in which,

Fig. 1 is a plan view of a preferred form of construction of the hose coupling.

Fig. 2 is an elevation thereof.

Fig. 3 is a perspective view of one of the two ,parts used in making the coupling, and Fig. 4 is a view similar to that shown in Fig. 2, of a modification in structure of the coiuoling. y l y Like reference characters refer yto like parts in the different figures of the drawing',

In the preferred form, shown in` Figs, 1 and 2, a. relatively narrow and` elongated fla-tstrip of metal, indicated at 1, is provided which, at one end has an ear 2 turned there- 55 from at an angle. This forms one of the two main members of the hose coupling and is common to both modifications thereof. Associated therewith, in the preferred form is a second member of sheet metal somewhat wider than the strip 1 and formed with oppositely extending sections 3 and 4 which extend from an inverted U-shaped part 5 formed between the ends of the second member, as shown. Near the free ends of said sections 3 and 4, openings 6 and 7, respectively, are made having a width such that the strip 1 may freely pass therethrough. If desired, the metal between the openings and the ends of the sections may be pressed upwa-rdly, as indicated at 8 and 9, the recess or depression on the under sides of said sections 3 and 4 being wide enough to receive the width of the strip 1. Also, for strength, the longer section 3 may be embossed longitudinally and between its side edges as at 10, this, however, being no essential feature of the invention.

The end of the strip 1 having the ear 2 thereon is passed through the opening 7 in t-he section 3, as shown, whereby the ear 2 is brought into substantial parallelism with the part 5. Openings being made through the ear 2 and the legs of the U-sh-aped part 5 in alinement, a stove bolt 11. is passed therethrough, the head thereof coming against the part 5, and a, nut 12 is threaded on to the end of the bolt against the ear 2. The position of the bolt may be reversed without changing the action in any respect.

The couplings are assembled as above described and shipped to the place of use. When used it is merely necessary to place the coupling around the hose with which it is to be used, and passthe free end of the strip 1 through the opening 6, allowing the end portion to pass through as far as it will go, or pulling the same through as far as possible by hand or with pliers, then bending the part extending through the opening back in a reverse direction, the end portion 1a, as shown, being left to remain or cut off as to excess if desired. Then the bolt is tightened until the coupling securely grips the hose around which it is placed. This is a very convenient and simple method of attachment, the user not having to thread the nut on to the bolt at any time in the process. Also the coupling is practically of universal application for all standard sizes' of hose, it beingrnerely necessary to draw the portion 'la through' farther for smaller sizes of hose than for the larger sizes.

In F ig. il, a somewhat modified form ot -struc'tu'reis shown. Thev 'strip 1 with ear 2 5 is the same.

from a single piece ot sheet metal having a section 18, at one end bent back upon itself for a distance, as at 111 and then turned upward to make an ear which 'lies in paralleliism with the ear @after the end of strip 1 carrying said ear has been passed through an vopening similar to opening 7 in the end of Athev section 13. The bolt 11 with nut l2 is 'used-to connectfthe parts, passing through 15 ears Zand 15. ln using the coupling, the free end portion ot the strip 1 is passed through openings made in the opposite end ot the section 13 and the overlying part 14 "and is bent back, in the same manner as be- .'20 tore described.` Ilhis construction is not as good as' thev iirst from` a manufacturing standpoint, requiring more expensive dies and being more costly to manufacture. i Otherwisefthere is no difference in the two constructions in so far as Ifunctions performed are concerned.

` I claim:

1. Afhose coupling, comprising one member or sheet metal formed with an opening 510 therethrough adjacent each end and between its 'ends with an outwardly yprojecting U- shapcd portion, a second Vvmember of relatively -narrow and elongated shape, formed -at one end Ywith an outturned ear, said vb5 end ofi-the second member being passed Ithrough one of' the openings in the'iirst member so thatthe ear .is brought into substantial. parallelism with saidU-shaped porl0 'shapedt portion andA ear and having a nut Aat its end threaded thereon,v substantially as and for the purposes described.

2. A' h'ose coupling, comprising a 1relatively short member formed 4trom Vsheet "'45 metal and having an opening inea'ch end portion thereof, a second men'iber ot'shcet metal narrower than the tirst member and' much longer Vthan `thellirst member'formed "at oneendi'with an outturiied ear, said end said second member and the'ear thereon I being-"passed through one of theop'cnings in thetirst memben means'projecting outward "from",vl the; first member ',"betweenl the ends thereof to' lie in l substantial parallelism with.
